Patented Nov. 10, 1931 UNITED STATES ESRAEL LANGERT, OF BROOKLYN, NEW YORK ELECTRIC LAMP GLOBE Application filed February 5, 1931. Serial No. 513,496.

This invention relates to electric lamp globes anddevices for mounting the same.

An object of this invention is to provlde a highly improved and novel means for mounting globes for electric lamps and the like illuminating devices, which shall be extremely simple to manipulate for attachlng or detaching the globe. A further object of this invention is to 1 provide in a globe mounting device of the character described, a hood constructed to permit heat and gases within the globe to readily circulate to the outside.

A still further object of this invention is 15 to provide a mounting device ofthe character described, which shall have improved means for effectively reflecting and diffusing the light within the globe.

Still another object of this invention is 20 to provide a neat, compact and rugged struc- "ture of the character described, which shall be comparatively inexpensive to manufacture, easy to assemble and disassemble and which shall yet be practical and eflicient to 2 a high degree in use.

Other objects of this invention will in part be obvious and in part hereinafter pointed out.

The invention accordingly consists in the 30 features of construction, combinations of elements and arrangement of parts which will be exemplified in the construction hereinafter described and of which the scope of application will be indicated in the following claims. In the accompanying drawings, in which is shown one of the various possible embodiments of this invention,

Fig. 1 is a side elevational view of a globe and mounting device therefor, embodying 40 the invention; 1

Referring now in detail to the drawings, 10 designates a lamp globe, housing an'elec- .Fig. 6 is a cross-sectional view takenon 'tric lamp or other illuminating device'(not shown) attached to mounting means 11, embodying the invention. The globe 10 is provided with a neck portion 13 here shown, as beingformed with an outwardly flaringrim 14. The mounting device 11 comprises a central cylindricalportion 15 to the top portion 16 of which may be attached, lamp sockets and suspension means of any'suitable-construction, whereby the globemay be suspended from a ceiling or the like support.

: Extending outwardly from said cylindricalportion 15 at the bottom thereof,fis a flange 17, preferably corrugated asshown at .18, and polished on the undersurface v19 thereof, whereby said flange acts as a reflector and diffuser for light from the illuminant within the globe. Extending upwardly from the outer portion 20 of said flange 17 is an upwardly and outwardly flaring annular wall 21 concentric with cylindrical portion 15 and adaptedto contact the inner surface 22a of said neck portion 13. I

Means is provided on' said mounting device 11 for engaging the inner surface of the outwardly flaring portion 22 of the lamp globe,

just beneath the neck portion 13, at a plurality of angularly spaced points, whereby said globe may be suspended from the mounting means. To this end a plurality of radially extending, angularly spaced plates or like members 24 are fixed, bymeans ofrivets 25 .or in any'other suitable manner, to the upper side of the flange 17, the outer end portions 26 of said plates being adapted to contact said flaring portion 22 of the globe. Preferably, two fixed plates 24 are provided, said plates being spacedsubstantially 120 from one another,,a'lthough any number of suitably spaced-members may be employed.

A third movable member 30 is provided .for contacting the flaring portion 22 of the globe at preferably a point thereon equally spaced from the plates24. To this end, the annular wall 21 is formed with a slot. 31 adjacent the flange 17 wide enough for the plate to extend therethru. The plate 30 is disposed radially and is adapted to slidably move on preferably the upper surface of the flange 17, and between a pair of guide members 34 and 35, which may be struck up from the wall of the flange. The plate 30 is provided with a central longitudinal slot 36, and extending through said slot is a rivet or eyelet 37 adapted to attach one end 38 of a spring 39 to the upper surface of the plate 30. The connection is such as to permit the plate 30 to slide. However, said spring 39 is provided with a downwardly bent portion 40 adapted to press against the upper surface of the plate '30. When said plate is moved to the outermost position thereof, as shown in Fig. 3, however, the portion 40 is adapted to snap over the inner end 41 of the plate to preventsaid plate 30 from being accidentally moved inwardly to release the globe. Extending upwardly from the plate 30 at the inner end 41 thereof and disposed on opposite sides of the spring 39 are a pair of integral handle members 42 formed with a beaded top portion 43. Said handle members 42 are adapted to be rasped by the fingers for moving the plate inwardly or outwardly, and also serve as guides for the spring 39.

It will now be clear that to remove the globe from the mounting device 11, it is merely necessary to move the plate 30 inwardly by properly manipulating the handles 42. The device 11 may then be t lted about the plates 24 thereof to bring the portion thereof adjacent the plate 30 out above the rim '14. The globe may then be properly manipulated by'a' side movement to disengage the same from the outwardly extending portions 26 of the plates 24.

The cylindrical portion 15 may be provided with an integral outwardly projecting annular bead and mounted on said bead 50 is a hood 51 having an inner rim 52 slidably receiving said cylindrical portion 15 and engaging and resting on the top of said bead.

The hood is provided with a portion 54 disposed above the rim 14 of the globe and the portion 55 of greater diameter than said rim, whereby a space is formed between the top rim of the globe and said hood. The

cylindrical portion 15 is furthermore provided with a plurality of openings .56 in the wall thereof, below the bead 50, where by heat and gases within the globe, may circulate through said opening and through said space 60. This construction prevents overheating of the globe.

In accordance with the modified construction illustrated in Figsfi and 6, themounting device 11a comprises a flange 17a likewise provided with two fixed radially extending plates or supports similar to plates 24. The movable support 30a however, is pivoted to F the flange 17d as at'62 adjacent the inner end thereof. The plate 30a projects through a slot 63 formed in the outer wall 21a of said member 11, said slot being of sufficient length to permit the plate 30a to be pivotally moved about the pivot 62 thereof from the full line position shown in Fig. 5 to the dotted line position shown in said figure, said latter po- Sition bringing the plate'into superimposed position with respect to the flange, and hence releasing the same from contact with the globe.

A handle member 65 comprising an upright post may be attached to the plate 3064 by means of. a set screw 66, extending through a curved slot '68 formed in said flange 17a. Thus, upon loosening theset screw (36, the handle 65 may be moved for pivotally mov ing the plate. The set screw may be tightened in any position of the plate for retaining the plate in various adjusted positions.

It will thus be seen that there. is provided a device in which the several objects of this invention are achieved, and which is well adapted. to meet the conditions of practical use.

A various possible embodiments might be made of the above invention, and as various changes might be made in the embodiment above set forth, it is to be understood that all matter herein set forth or shown in the a.c-

coin mnying drawings is to be interpreted as illustrative and not in a' limiting sense.
